I would rather teach Maths and adapt to the class or student rather than plonking a book in front of them.
What’s the difference between an exercise from a worksheet and an exercise from a textbook?
I had to strong-arm our latest student teacher into using a textbook. She was working herself into the ground creating resources, trying to find stuff on TES etc. The university had sneered at textbooks and said it was ‘lazy’ to use them. I said ‘There’s a good exercise for that topic in this textbook, JUST USE IT FFS’. Decent textbooks have well-written exercises with increasingly difficult questions and extension questions. Having the answers in the back is brilliant at GCSE - you can make sure that bright classes check their work as they go along, it’s instant feedback.
I still use the same GCSE textbooks that I used when I started teaching over a decade ago. They are falling apart now and only held together with ‘Maths is gay’ graffiti. I use them regularly, with a variety of classes, but a minority of lessons. I know which topics they’re really good for, and I know I can grab them if I need extension work on a topic or a class need more practice. Obviously they don’t cover the new topics on the GCSE
The school has bought a few different sets of GCSE textbooks since then, and none are as good. The ones that were rushed out for the new GCSE were so bad that we didn’t buy any of them.
I think some people who are anti-textbook have never actually seen a decent one, or think that the kids are supposed to teach themselves from them. Of course not. The teacher teaches, the textbook replaces the worksheet.
